Extreme megadrought in Afro-Asian region likely had consequences for Paleolithic cultures How severe can climate change become in a warming world? Worse than anything we've seen in written history, according to results of a study appearing this week in the journal Science. An international team of scientists led by Curt Stager of Paul Smith's College, New York, has compiled four dozen paleoclimate records from sediment cores in Lake Tanganyika and other locations in Africa. The records show...

Researchers are now using sedatives to save endangered whales tangled in fishing line so they can pull them closer and cut the potentially fatal gear away. The method was used January 15 off the Florida coast to free a young North Atlantic right whale from about 50 feet of line wrapped through its mouth and around its flippers. "It's a big step for us," Michael Moore, a senior research specialist at the Woods Hole Oceanographic Institution in Massachusetts who was on the rescue team, told The...

Temperatures of North Atlantic Ocean currents flowing north into the Arctic Ocean are at their highest levels in nearly 2,000 years, and could ultimately lead to summers that are ice-free in the North Pole region, researchers claim in a new study. The waters of the Fram Strait, which is located at the northern end of the Gulf Stream near Greenland, have gotten approximately 3.5 degrees Fahrenheit warmer over the past century, study leader Robert Spielhagen of the Academy of Sciences,...

Getting a bird's eye view of North Atlantic right whales in a bid to save them from extinction; Charleston, S.C. survey flights from November 15, 2010 through April 15, 2011; St. Simon's Island, Ga. Survey flights from December 31, 2010 through March 31, 2011 NEW YORK, Nov. 15, 2010 /PRNewswire-USNewswire/ -- EcoHealth Alliance (formerly Wildlife Trust), is gearing up for the organization's annual aerial surveys for the protection of endangered North Atlantic right whales. For the fourth...

Global warming today could have similar effects on ocean currents and could accelerate climate change The Atlantic Ocean circulation (termed meridional overturning circulation, MOC) is an important component of the climate system. Warm currents, such as the Gulf Stream, transport energy from the tropics to the subpolar North Atlantic and influence regional weather and climate patterns. Once they arrive in the North the currents cool, their waters sink and with them they transfer carbon from...

Boulders deposited by an ancient glacier that once covered the summit of Mauna Kea on the island of Hawaii have provided more evidence of the extraordinary power and reach of global  change, particularly the slowdown of a North Atlantic Ocean current system that could happen again and continues to be a concern to climate scientists. A new study has found geochemical clues near the summit of Mauna Kea that tell a story of ancient glacier formation, the influence of the most recent ice...

A team of scientists has returned to the North Atlantic to gather more data on the Icelandic volcanic eruption that took place earlier this year. The researchers are studying whether iron within the vast volcanic ash cloud entered the ocean, causing an extended bloom of tiny organisms known as phytoplankton. The scientists have recorded "enhanced levels" of iron in samples they have collected. The most recent project follows an earlier cruise, which was carried out in the spring. The...

North Pacific circulation radically changed by past post-glacial warming Toward the end of the last ice age, a major reorganization took place in the current system of the North Pacific with far-reaching implications for climate, according to a new study published in the July 9, 2010, issue of Science by an international team of scientists from Japan, Hawaii, and Belgium. Earth's climate is regulated largely by the world ocean's density-driven circulation, which brings warm surface water to...

Just like people in a bar or other noisy location, North American right whales increase the volume of their calls as environmental noise increases; and just like humans, at a certain point, it may become too costly to continue to shout, according to marine and acoustic scientists. "The impacts of increases in ocean noise from human activities are a concern for the conservation of marine animals like right whales," said Susan Parks, assistant professor of acoustics and research associate,...

A chain of past natural events may hold lessons for the future Scientists still puzzle over how Earth emerged from its last ice age, an event that ushered in a warmer climate and the birth of human civilization. In the geological blink of an eye, ice sheets in the northern hemisphere began to collapse and warming spread quickly to the south. Most scientists say that the trigger, at least initially, was an orbital shift that caused more sunlight to fall across Earth's northern half. But how...

North Atlantic Right Whale, Eubalaena glacialis
2013-08-26 11:17:56

The North Atlantic right whale (Eubalaena glacialis), also known as the black right whale or the northern right whale, is one of three right whales in the Eubalaena genus. It can be found in a small population of about 396 individuals in the western North Atlantic. If it does occur in the eastern North Atlantic, experts assert that it only numbers in the tens, making it nearly extinct in that area. This species migrates into the western North Atlantic to feed in the spring, summer, and fall...

The Humpback Whale (Megaptera novaeangliae) is a mammal, which belongs to the baleen whale suborder. It is a large whale: an adult usually ranges between 40"“50 ft (12"“16 m) long and weighs approximately 79,000 pounds (36,000 kilograms, or 36 tons. It is well known for its breaching (leaping out of the water) and its unusually long front fins. The Humpback Whale lives in oceans and seas around the world, and is regularly sought out by whale-watchers. Feeding The Humpback Whale...
